Ozone “hole” appears stable

BBC Science News reports that the ozone layer over the Antarctic seems to be on the road to recovery.
It’s not all good news though. Ozone depletion has stabilised, but it will take decades for a full recovery. The report also states that CFC replacements contribute to global warming, without going into any detail on this aspect.
There’s a nice discussion over at Asymptotia, which points out that once in a while, humans can get it right. The problem was identified, the solution was devised and for once, the world got together and acted for the common good.
